The interrupting ratings are substantial: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 6 kA at 690 V — so it handles high-fault-capacity mains feeders without cascading upstream. The 250 A rating holds flat through 50 °C, then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C; in a warm panel you size for the derated figure, not the nameplate.
Trip unit, auxiliaries, and communication
Communication function is present, so this breaker can report status and trip events to a higher-level system. The basic switch module is order code 3VA2225-6JQ32-0AA0, and the integrated auxiliary trip is 3VA9688-0BL30 — useful to know if you're stocking spares for the same panel.
